DC-DC开关降压稳压器, 可调, 2.6V-5.5V输入, 1.4MHz, 750mA, QSOP-16
The from Products is a dual, 180° out-of-phase, 1.4MHz, 750mA step down regulator with POR and RSI/PFO in 16 pin QSOP package. It is a dual-output current mode PWM buck regulators operate from 2.6V to 5.5V input and deliver a minimum of 750mA on each output. It operates at a fixed 1.4MHz to reduce output inductor and capacitor size and cost. Switching the regulators 180° out-of-phase also reduces the input capacitor size and cost. Ceramic capacitors can be used for input and output. The output voltages are programmable from 1.2V to VIN using external feedback resistors, or can be preset to 1.8V or 3.3V for output 1 and 1.5V or 2.5V for output 2. When one output is higher than 1.2V, the second can be configured down to sub-1V levels. Output accuracy is better than ±1% over variations in load, line and temperature. Internal soft-start reduces inrush current during start-up.
